The main types of greenhouses: Greenhouse. The night before the slope was covered with insulation, east, west and north walls of the envelope single slope plastic greenhouse, collectively known as the Greenhouse. Its prototype is a single slope glasshouse, front slope covered with translucent plastic film instead of glass materials that evolved into the early solar greenhouse. Greenhouse is characterized by good insulation, low investment, energy saving, very suitable for China's underdeveloped rural use. The height of the north-south span Greenhouse: height and north-south span, should be based on the latitude to be. Because height and angle determines the span greenhouse nursery greenhouses offer lighting surface, angle light plane around the sun but also the size of the angle of incidence. Ensure a greater incidence rate of sunlight greenhouse nursery price, it should be less than 40 degrees angle of incidence. Because the sun's angle of incidence of light projected rate closely. Its angle of incidence in the range of 0-40 degrees, with the angle of incidence increases nursery greenhouses, light incident rate decreased, but did not change significantly when the incident angle is greater than 40 degrees later, with the angle of incidence increases, the transmittance rate was even dramatically.
